sorry, forgot to answer first question.
if the mics are set up the way the ears are then the resulting combined
signal will sound very 3d.  you just need two variables, the angle between
the mics and ( i dont know a good value for this ( perhaps around 90
degrees))  the distance between the mic heads.  i think around 8 or 9 inches
is good.  ( 17.6 cm - 19.8 cm  for you internationals out there).
try different locations near or far from your source the get different
levels of natural reverb.  closer gives more source, less reverb.  further
away gives more reverb mixed with the source sound.

i have a stereo dat mic that gives the best stereo response ive ever heard.
it is an audio-technica at822 stereo mic for those interested.
